Harry is a HS student with too much time on his hand when he was homebound during the COVID-19 pandemic. He designed a method how he can throw pebbles over the 2.1-m fence in his backyard such that they land in a pot on the ground of his neighbor’s property: he stands 6.7 m in front of the fence and throws a pebble from 1.7-m height such that the highest point is at 1.5 m right above the fence.
a) We use t1 for the time for the pebble to travel from Harry’s hand to the highest point and t2 for the time for the pebble to travel from the highest point until it falls into the pot. Find the ratio t1/t2!
b) Find the distance D of the pot from the fence!
c) Find the launch speed of the pebble!
d) Find the direction in which he throws the pebble!
